实验要求：最少两台服务器，而且这两台服务器属于同一台主机
先在两台服务器上用yum安装screen
yum install screen -y
第一台服务器创建一个房间
screen -S +房间名
[root@localhost ~]# screen -S an
[root@localhost ~]# ls
anaconda-ks.cfg Documents initial-setup-ks.cfg Pictures Templates
Desktop Downloads Music Public Videos
[root@localhost ~]#
第二台服务器查找screen的房间
screen -ls
[root@localhost ~]# screen -ls
There is a screen on:
23233.an (Attached)
1 Socket in /var/run/screen/S-root.
找到第一台服务器创建的房间，第二台服务器加入第一台服务器创建的房间
联通以后，两台服务器就可以同步进行
screen -x +房间名
[root@localhost ~]# screen -x an
[root@localhost ~]# ls
anaconda-ks.cfg Documents initial-setup-ks.cfg Pictures Templates
Desktop Downloads Music Public Videos
[root@localhost ~]#
在房间输入 exit 会退出并关闭房间
[root@localhost ~]# ls
anaconda-ks.cfg Documents initial-setup-ks.cfg Pictures Templates
Desktop Downloads Music Public Videos
[root@localhost ~]# ^D
bash: : command not found...
[root@localhost ~]# ctrl +d
bash: ctrl: command not found...
[root@localhost ~]#
[root@localhost ~]# Ctrl+a
bash: Ctrl+a: command not found...
[root@localhost ~]# Ctrl+a
bash: Ctrl+a: command not found...
[root@localhost ~]#
[root@localhost ~]#
[root@localhost ~]# exit
[root@localhost ~]# screen -S an
[screen is terminating]
[root@localhost ~]#
注：这两台服务器必须在同一台主机
